War of the Edelstens: Brynne and Geoffrey's split turns into a living nightmare as couple continue to share one-bedroom apartment

They made the decision to end their marriage last year, but socialite Brynne Edelsten and her soon-to-be ex husband are still living under the same roof.

The difficult living situation has almost reached breaking point, according to this week's issue of Woman's Day.

Geoffrey, 70, is said to be sleeping on the couch while Brynne is in the apartment's only bedroom.

An insider close to the Australian millionaire told the magazine how the Melbourne party girl has been bringing friends back to the apartment to keep drinking after a night out - and it's getting on Geoffrey's nerves.

'She has no respect whatsoever,' the source told Woman's Day. 'There he is trying to sleep, while she and her mates crank up the stereo full blast.'

The couple seem to be at the end of their tethers living under the same roof, with the source from Geoffrey's camp claiming that former waitress Brynne 'screams and shouts if she doesn't get her own way'.

The opulent inner-city love nest of the flamboyant pair features floor-to-ceiling windows that take in the view across Melbourne and his-and-hers plasma screens, a tour of the residence by the Herald Sun revealed in 2011.

Plush white leather lounges contrast with unusual glizy installations that hang from the ceiling, and the unit is littered with picture frames filled with photos of the couple in happier times.

It looks like the 31-year-old American is partying through the pain after a tough start to the year.

After announcing her shock split from Geoffrey amid allegations he'd been unfaithful, Brynne also experienced the loss of her grandmother.

The couple are reportedly at each others throats living in such close quarters

The former reality star took to her Facebook to make the sad announcement, writing 'Today we lost my beautiful grandmother. Thank you all for your prayers and thoughts. All through my life she told me "No matter where you go or what you do, you'll always be my Brynney.

'I will love you and miss you forever, Grandma... and I'll always be your Brynney.'

The usually bubbly personality spoke about the decision to end her marriage last month in New Idea.

She said rumours that the 70-year-old had whisked a woman he met online for a weekend away to Miami, while they were still married, ultimately ended their union.

She said she struggled to believe her husband of four years when he denied it.

According to reports, Geoffrey had sparked up a relationship with the woman over sugardaddyforme.com and then treated her to a holiday in March 2012.

Brynne said at the time she was able to forgive Geoffrey, but over time it became hard for her to forget.

Brynne said the couple then turned to counselling to repair their marriage, but it in the end the damage was already done.

Geoffrey has only made limited public comment about the end of his marriage, telling the Herald Sun 'Yes, I am very, very sad'.

'I was saying to her yesterday, this is the last thing I wanted.

'I just think she is fantastic. I just hope that everything goes well for her, I certainly will be supporting her. I feel pretty miserable actually.'

MailOnline reached out to spokespeople for Brynne and Geoffrey for comment on Monday but did not receive an immediate reply.
